Call Button
In case of a threatening situation –
confrontational, aggressive behaviour or physical harm
– the employee sets off a silent call via the discreetly
placed call button.
Feedback will be immediately available via an LED on
the call button:

A) No LED: Resting state.

B) Red LED: Sending the call from the radio button.

C) Green LED: Call is successfully transmitted.

Server

The server can be considered as control center of the
overall system.
Physically, it is a conventional, LAN-based MS Windows
Personal computer on which a special component
(the „Silent Radio Call“-Server) is installed and
can be executed.

Gateway
The Gateway provides a link between Call Button,
Server and Radio-Displays.

It routes the call from a Call Button to the Radio-
Displays and sends corresponding conformations
back, in order to give a feedback for the affected persons.

One Gateway can support a large number of Radio-
Displays and Call Buttons inside of its radio range.

Radio-Display

The radio display receives the forwarded notification from the gateway.

Features & elements of the radio displays:

- Display at the Room ID

- Display the radio calls

- Acoustic signal

- LED display

- Confirmation button

In the two-sided version the display additionally shows
e.g. the employees name.
